I'm going to revert the duplicate status because bug #744101 has no discussion whereas this bug has analysis about the causes of the bug and a linked branch fixing the issues. The retraced stacktrace in bug #744101 would be useful only if the issue was still unclear. But for completeness: Here the links to the stacktraces:
